I think you're overlooking a key strength with the osm database, that
all the map features are integrated, e.g. if a kiosk is mapped to be
three meters to the left of the entrance to the building, and that is
also the ground truth, then you have that fact of their interrelation.
With different datasets from different sources, you lose it.
